Field of the Invention Insectrepellant assembly.

2. Description of the Prior Art In the past few years, numerous volatileliquid organic materials have been developed that tend to repel insectssuch as mosquitos and the like. Such materials may be distributed in anarea that is to be protected from insects by being sprayed on surfacesadjacent thereto, or into the air as an aerosol mist. Also, suchmaterials, if they are non-toxic, may be applied to the skin or garmentsof the user.

However, such methods of application are unsatisfactory, in that whenthe repellant is applied to the skin it is at least partially absorbedinto the body of the user, and this absorbed portion, of course, beingineffective in repelling insects. There is some evidence that volatileliquids used as repellants whether toxic or nontoxic on the skin andabsorbed into the body of the user create damaging residual factors inthe health of the user. When the repellant is applied to a surface, thesurface may be too far from the user for the repellant to be effectivein protecting him, and this is likewise true of applying the repellantas an aerosol spray, for even a light wind or breeze will dissipate theaerosol mist to render the same ineffective against insects.

The primary purpose in devising the present invention is to supply asimple, inexpensive insect repellant assembly that may be removablysecured to the garment or a desired body portion of a user and with theassurance that the part of the users body adjacent the assembly will beprotected from the biting action of insects, such as mosquitos, gnatsand the like.

SUMMARY OF THE INVENTION The insect repellant assembly includes arelatively small absorbant pad which pad contains a volatile insectrepellant, with the pad secured to the first side of a pliable barriersheet, and the second side of the sheet being coated with a film of apressure sensitive adhesive. A number of protective sheets are provided,which prior to the assembly being used are secured thereto, and extendover the absorbant pad and the film of adhesive to protect the same frominadvertent contact by a user. When the device is used, the protectivesheets are peeled therefrom, and the barrier sheets and supported padare removably secured to a desired portion of a person that is to beprotected from insects, or a desired location on a persons garment. Whenthe assembly is so applied, the volatile liquid repellant evaporatesslowly from the pad, and to the extent that insects such as mosquitos,gnats or the like are discouraged from coming close to the portion ofthe user on which the assembly is removably mounted. After the assemblyhas served its intended purpose, it is removed, and discarded.

DESCRIPTION OF THE PREFERRED EMBODIMENT A first form A of the flyinginsect repellant assembly is shown in FIG. 1, where it will be seen thatthe invention includes an elongate pad 10 that is centered on anelongate pliable barrier sheet 12. The pad 10 when so disposed on thesheet 12 covers only a portion of a first upper surface thereof, and thesheet 12 accordingly has uncovered end portions 12a as shown in FIG. 2.The pad 10 contains a quantity of a volatile liquid insect repellant(not shown) of the type such as is presently commercially availablewhich may contain the following organic insect repellant materialN-diethyl-metatoluamide.

The barrier strip 12 is impervious to the liquid insect repellant (notshown), and prevents the repellant being absorbed by the skin of theuser.

The surface end portions 12a have end portions of two protective pliablestrips 14 and 14a secured thereto by conventional means, with theprotective sheets overlapping the adjacent end portions of the secondsheets 14a as illustrated in FIG. 1 and being removably secured theretoby a pressure sensitive adhesive (not shown). The second side of thebarrier sheet 12 as may best be seen in FIG. 3 is coated with a film 16of a pressure sensitive adhesive. Two second sheets 18 and 18a aresecured to the barrier sheet end portions 12a as may be seen in FIG. 2,and overlap one another at substantially the center of the pad 10, andare removably secured to one another by pressure sensitive adhesive (notshown). When it is desired to use the first form A of the invention, thesheets 14 and 14a are stripped therefrom, as are the protective sheets18 and 18a. The pad 10 and barrier sheet 12 as shown in FIG. 3 may thenbe removably secured to a desired body portion of the skin of a user(not shown) or a users garment (not shown), with the volatile insectrepellant thereafter evaporating from the pad 10 to discourage insectslighting on or biting a portion of the user (not shown) adjacent the pad10. The protective sheets 14 and 14a, and 18 and 18a serve to protectthe pad 10 and pressure sensitive adhesive film 16 being inadvertentlycontacted by user (not shown) prior to the first form A.

The second form B of the invention is shown in FIG. 4 that includes anelongate pad of an absorbent material that contains a volatile liquidinsect repellant (not shown) and this pad being of less length than arectangular pliable sheet 22 that is impervious to the repellant and onwhich the pad 20 is mounted and secured thereto by conventional means(not shown).

The pad 20 only partially covers the first surface of the barrier sheet22 and as a result the barrier sheet 22 has uncovered end portion 22a.The barrier sheet 22 on a second side thereof is covered with a film 24of a pressure sensitive adhesive. The second form B of the invention asmay best be seen in FIGS. 4 and 6 includes a rectangular frame 26 thatextends around the pad 20, the frame being secured to the first side ofthe barrier sheet 22 by conventional means, and the frame formed from amaterial impervious to the repellant. The second form B of the inventionalso includes a first pair of protective sheets 28 and 28a that have endportions thereof secured to the ends 22a of the barrier sheet as shownin FIG. 6, with a portion of the protective sheet 28a overlapping theprotective sheet 28 and being removably secured thereto by pressuresensitive adhesive means (not shown). A second pair of protective sheets30 and 30a have the end portions thereof secured to the second surfacesof the barrier sheet 22, with the sheet 30a extending over the sheet 30and removably secured thereto by a pressure sensitive adhesive (notshown). When the protective sheets are disposed as shown in FIG. 6 thesheets 28 and 28a cooperate with the frame 26 and barrier sheet 22 tocompletely envelope the pad 20 and prevent the volatile insect repellant(not shown) evaporating therefrom.

When it is desired to use the second form B of the invention, theprotective strips 28, 28a and 30 and 30a are peeled therefrom anddiscarded, with the barrier sheet 22, frame 26 and pad 20 beingremovably secured as a unit to a desired portion of a user or a usersgarment. When the second form B of the invention is so mounted on theuser or the users garment the volatile insect repellant evaporates fromthe pad 20 and discourages flying insects such as mosquitos, flies orthe like from coming into contact with the user or users garments, onwhich the second form B of the invention is mounted.

A third form C of the invention is shown in FIG. 7 that includes anabsorbant pad 32 that contains a volatile liquid insect repellant, withthe pad being encased in an envelope 34 formed from a rigid plasticmaterial or the like that is secured to a first surface 36 of a barriersheet 38 that is formed from a pliable sheet material. The secondsurface of the barrier sheet 38 is coated with a pressure sensitiveadhesive 40 to permit the assembly C to be removably secured to adesired portion of a user or users garment (not shown). The envelope 34,if desired, may have weakened areas 42 formed therein that may bepunched out when the invention C is desired to be used to permit thevolatile liquid insect repellant to escape from the pad 32 as a vapor.Such vapor discourages the approach of flying insects to the portion ofa user or users garments on which the third form C of the invention ismounted.

A fourth form D of the invention is illustrated in FIG. 9 that includesa circular pad 44 that contains a volatile liquid insect repellant (notshown) with the pad being disposed within the confines of a circularrigid frame 46 that has two generally semicircular protective sheets 48and 48a secured to the upper first surface 50 thereof, with the sheet48a overlapping the sheet 48 and being removably secured thereto by apressure sensitive adhesive (not shown). The second surface 52 of thering 46 has a barrier sheet 54 secured thereto which barrier sheet onthe lower surface thereof, as viewed in F IG. 9, is coated with apressure sensitive adhesive 55.

Two protective sheets 56 and 56a are secured to peripheral edge portionsof the sheet 54, with the second sheet 56a overlapping the first sheet56 and being removably secured thereto by pressure sensitive adhesive.When it is desired to use the fourth form D of the invention, theprotective sheets 48 and 48a and 56 and 56a are peeled therefrom toexpose the pressure sensitive film 55, which film is used to removablysecure the fourth form D of the invention to a desired body portion ofthe user or users garments (not shown). The volatile liquid repellantevaporates from the pad 44 when the invention D is so mounted on a useror users garment, and in the vapor thereof discourages flying insectssuch as mosquitos, gnats, or the like from approaching the user.

It will be particularly noted in both the second, third and fourth formsof the invention that the volatile liquid repellant is sealed fromcontact with the ambient atmosphere and as a result there is little orno loss of the repellant prior to the time the invention is placed in anoperable condition on a desired portion of a user or users body aspreviously described.

Although the invention has been illustrated and described in fourdifferent forms it will be apparent that these forms may be of othershapes if desired such as a triangular, ellipse or the like and stilloperate in the same manner as previously described.

The use and operation of the invention has been described previously indetail and need not be repeated.
